Understanding the Significance of Nested Stats (GTM)

(EDIT: I pasted some scrubbed output in a "comment" below. I hope it makes my question clearer)

We recently updated our GTM to version 12.1.4 and I'm seeing some unexpected results in iControl REST's output. If I query a particular pool member that I know has been disabled, I get two rounds of status.availbilityState, status.enabledState and status.statusReason back, and they don't match:

          "status.availabilityState": {
        "description": "available"
      },
      "status.enabledState": {
        "description": "enabled"
      },
      "status.statusReason": {
        "description": "Available"
      }
`


Then, further nested is another JSON response, and it's reporting accurate state:

`                      "status.availabilityState": {
                    "description": "available"
                  },
                  "status.enabledState": {
                    "description": "disabled"
                  },
                  "status.statusReason": {
                    "description": "Available: disabled directly"
                  }
`

What's the difference between these two, and why aren't they the same? Even something as simple as this cURL command returns the wrong value:


`[user@host ~]$ curl -k --user f5User:${RD_SECUREOPTION_F5_PASSWORD} -X GET -H "Accept: application/json" https://${RD_OPTION_GTM_SERVER}/mgmt/tm/gtm/pool/a/Pool-myservice-sts.gslb-int.mydomain.com/members/~Common~f5-ALB-PAIR:IP_ADDR-443/stats?\$select=status.enabledState | jq '.'
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   287  100   287    0     0   1131      0 --:--:-- --:--:-- --:--:--  1134
{
  "entries": {
    "https://localhost/mgmt/tm/gtm/pool/a/Pool-myservice-sts.gslb-int.mydomain.com/members/~Common~f5-ALB-PAIR:IP_ADDR-443/~Common~Pool-myservice-sts.gslb-int.mydomain.com:A/stats": {
      "nestedStats": {
        "entries": {
          "status.enabledState": {
            "description": "enabled"
          }
        }
      }
    }
  }
}

Thanks!

    Hello syncretism.

     

    It's slightly different

     

    • enabledState - User defined availability (Disable, Enable, ForceOffline)
    • statusReason - Environment availability (Green, Blue, Red, Yellow)

    KR, Dario.
